Lid

What is the weight of concrete cover (lid) to round shape well with a diameter 1.8 m, if the thickness of the cover is 11 cm? 1 m3 of concrete weighs 2190 kg.

Correct result:

m =  613 kg

Solution:

m=ρV=ρπr2h m=π2190(1.8/2)211/100=613 kgm = \rho V = \rho \pi r^2 h \ \\ m = \pi \cdot 2190 \cdot (1.8/2)^2 \cdot 11 / 100 = 613 \ \text{kg}



We would be very happy if you find an error in the example, spelling mistakes, or inaccuracies, and please send it to us. We thank you!
